However, they are based on strong assumptions and do not generalize well. When an image is reflected on a surface, the surface usually scatters the light a little and makes the reflection a little blurry. Once the entire window is soapy, turn the squeegee over. This is useful, for example, when a dark surface in shadow (such as the interior of a cave) needs to be brighter in order to make detail visible. Mist a thin layer of your cleaner on your windshield.
